Error reading from database when trying to duplicate an assignment in Moodle 3.1

[sscott1]

Hi,

I'm hoping someone could help me.

Any feedback is appreciated.

I have been having an issue duplicating items/assignments within a course in Moodle 3.1.9. When clicking duplicate item I receive an error message stating 'error reading from database' from what I can tell it seems related to the tables that support the tab display activity module.

This issue surfaced after upgrading from 2.7 to 3.1

I have reported the issue in Moodle tracker and Moodle discussion group to no avail.

Here is some of the debug information:

Debug info: Unknown column 't.intro' in 'field list' SELECT
t.id, t.intro FROM mdl_tab t JOIN mdl_backup_ids_temp b
ON b.newitemid = t.id WHERE b.backupid = ? AND
b.itemname = ? [array ( 0 =>
'5a5cd0fe64125f724465d3537cbbe3cf', 1 => 'tab', )] Error
code: dmlreadexception
